我正在使用CentOS 6.6。因此我没有Python所需的最新(2.7系列)软件包。我已经将Python 2.7.9从源码安装到/usr/local/lib/python2.7:

现在我有一个使用pysphere的脚本,它曾经工作正常(并且在其他2.6和2.7的机器上运行正常)但是当我用我当前的设置运行它时我得到了这个:
$ python main.py
Connecting to vSphere...

这里打破了什么?
答案 0 :(得分:1)
我已经晚了几年,但我自己也遇到了这个问题,并找到了一个解决方案。如果将来有人偶然发现这个帖子,我就会发表评论。
原因为什么会发生这种情况(这是Patryk的问题),Python的httplib.HTTPSConnection以前没有默认验证SSL证书。从Python 2.7.9开始,SSL validation is required。如果ESX服务器的SSL证书存在问题,则连接将失败。
不幸的是the pysphere library is no longer maintained。
假设您尝试在私有安全环境中使用pysphere库,可以将以下补丁应用于pysphere / ZSI / client.py文件:
294c294,295
< self.local.h = transport(netloc, None, **self.transdict)
---
> import ssl
> self.local.h = transport(netloc, None, context=ssl._create_unverified_context(), **self.transdict)
解释:pysphere库使用httplib.HTTPSConnection
建立与ESX服务器的连接。如果遇到SSL证书问题,则会因上述异常而失败。要恢复Python 2.7.9之前的行为,您需要告诉httplib.HTTPSConnection
不验证SSL证书。
